/*
* TBBC UI kit: the visual language of the home page and /rating-widget/, for inner pages.
* How to use: sites/tbbc.app/ui/README.md. Everything is scoped under .tbbc, so loading this
* file on a page never restyles what is outside a .tbbc element.
*
* Load with the brand fonts:

*
*
* Brand rules (docs/business/brand.md section 9): black, blue and white only. "Working" glows
* blue, "broken" goes white/grey. Red only for form validation. The blue/white glitch on hover
* and keyboard focus is the brand signature.
